A process for preparing aqueous dispersions of polymers containing oxazoline groups, by aqueous emulsion polymerization initiated by free radicals. The polymerization are carried out in two stages. In the first polymerization stage, an &#x3b1;,&#x3b2;-monoethylenically unsaturated compound having at least one acid group, an monoethylenically unsaturated compound having at least one carboxylic acid amide group, a monoethylenically unsaturated compound having at least one carboxylic acid amide group are copolymerized. In the second polymerization stage, a monoethylenically unsaturated compound having at least one oxazoline group, a monoethylenically unsaturated compound having at least one carboxylic acid amide group and an ethylenically unsaturated compound are copolymerized with the final product from the first polymerization stage.

Aqueous dispersion of an oxazoline group-containing polymer

Aqueous polymer dispersion as a binder for particulate and/or fibrous substrates.

Method for producing an aqueous binding agent dispersion

Aqueous binder composition for granular and/or fibrous substrates, where the binder contains i) a copolymer constructed from ethylenically unsaturated monomers; and ii) lignin.
